1895.] On the Question of Dielectric Hysteresis. 



Table I.

The ratio derived from the first twelve values is 1 + srVo" 

 derived from the second twelve values is 1 TO 3-5-0' The best 

 values of the ratio derived from all 24 values approximates still 

 more closely to unity. 



Hence the position of the point Q in the diagram is indistinguish- 

 able from the position of the point P; and we may conclude that 

 when time has been given for viscous effects to subside the charge of 

 the condenser is the same for a given value of the potential difference, 

 whether that value has been arrived at from higher or from lower 

 values than itself.
